Monday’s above-average warmth may be giving us a late taste of summer, but forecasters say a dramatic change is in store over the next few days, with the first rain of the season expected to douse the area as temperatures drop by as much as 25 degrees.
The high-pressure system that’s been bringing us unusually warm weather will give way to a low-pressure system moving in from the north starting Tuesday.
Forecasters said the region will see a roughly 25-degree drop in temperature by Wednesday. According to the National Weather Service, rain could start falling Tuesday night, with wet conditions continuing into Thursday. The area is expected to get between a quarter-inch and three-quarters of an inch of rain, according to the NWS.
Forecasters said the chance of showers will “develop after midnight Tuesday with the best chance occurring over L.A. County.”
“The best chances of rain will be Wednesday morning and afternoon with rain tapering off overnight Wednesday and pretty (much) ending by early Thursday afternoon,” according to the NWS.
Forecasters noted that Orange and San Diego counties are likely to receive most of the rain from the system.
